QT60161B-AS

Overview

The QT60161B-AS is a capacitive touchscreen controller from the QMatrix series, manufactured by Microchip Technology. It features a 2-wire interface and supports 10-bit or 16-bit resolution for accurate touch detection. The device operates within a supply voltage range of 3.3V to 5V and draws a typical supply current of 25 mA. Housed in a 44-TQFP package measuring 10x10 mm, it is designed for robust performance in industrial and commercial environments.

Feature Summary

• Capacitive sensing technology with QMatrix architecture
• Supports 10-bit and 16-bit resolution modes
• Utilizes a 2-wire serial communication interface

Applications

• Industrial control panels requiring durable touch input
